    • An automatic tuning procedure can be used to allow a small, high efficiency ferrite antenna assembly to be used in various FM frequency based devices. The ferrite antenna can take the form of a rod or flat disk, for example, which can use a pick-up coil and tuning coil to provide sufficient signal strength using a small FM antenna. A balanced amplifier can be used to provide differential input in order to further reduce noise. A microcontroller can determine the strength of the FM signal at various frequencies and can automatically tune the operating frequency to optimize system performance.
    • 可以使用自动调谐程序来允许在各种基于FM频率的装置中使用小型,高效率的铁氧体天线组件。 铁氧体天线可以采用例如可以使用拾波线圈和调谐线圈的杆或平盘的形式,以使用小的FM天线提供足够的信号强度。 平衡放大器可用于提供差分输入,以进一步降低噪声。 微控制器可以在各种频率下确定FM信号的强度,并可以自动调整工作频率以优化系统性能。

    • A rotating toy may then include a hub having a central axis and a lower portion; a plurality of counter rotating blades extending outwardly from the lower portion of the hub, the plurality of counter rotating blades having a tip connected to an outer ring; a single means for rotating the hub and blades sufficiently quickly to generate a major portion of the lift generated by the aircraft through the single rotating means; and the hub having an upper portion above the plurality of counter rotating blades and above the single rotating means such that the aircraft includes a center of gravity above the plurality of counter rotating blades to provide a self-stabilizing rotating toy. In furtherance thereto the single rotating means may be secured on the central axis and positioned below the counter rotating blades.
    • 然后,旋转玩具可以包括具有中心轴线和下部分的轮毂; 多个反向旋转叶片,其从所述轮毂的下部向外延伸,所述多个反转叶片具有连接到外圈的尖端; 用于使轮毂和叶片足够快地旋转以产生飞行器通过单个旋转装置产生的升力的主要部分的单个装置; 并且所述轮毂在所述多个反转叶片上方具有上部并且在所述单个旋转装置上方,使得所述飞行器在所述多个反向旋转叶片之上包括重心以提供自稳定旋转玩具。 为了促进这一点,单个旋转装置可以固定在中心轴线上并且位于反转叶片下方。
